   Stravum — About page brutalist scope.

   Loaded ONLY on the About page via the stravum-about-brutalist mu-plugin, and
   every rule is additionally namespaced under .sab (present on each top-level
   section of that page). Two independent guards, so this file can have zero
   effect anywhere else even if it were somehow loaded on another request.

   What this file owns: the JetBrains Mono label/mono register, the heavy
   uppercase wide-tracking voice, hard borders, the hero watermark, and the
   hover behaviours the design depends on. Plus Jakarta Sans and Geist are NOT
   touched — they stay the connecting thread to the rest of the brand.
